Heller myotomy is a surgical procedure [1] in which the muscles of the cardia (lower esophageal sphincter or LES) are cut, allowing food and liquids to pass to the stomach. It is used to treat achalasia , a disorder in which the lower esophageal sphincter fails to relax properly, making it difficult for food and liquids to reach the stomach.
The per-oral endoscopic myotomy, or POEM, is a minimally invasive surgical procedure for the treatment of achalasia wherein the inner circular muscle layer of the lower esophageal sphincter is divided through a submucosal tunnel. [1]
The shortcoming of laparoscopic esophageal myotomy is the need for a fundoplication. On the one hand, the myotomy opens the esophagus, while on the other hand, the fundoplication causes an obstruction. Recent understanding of the gastroesophageal antireflux barrier/valve has shed light on the reason for the occurrence of reflux following myotomy.
Myotomy is a surgical procedure that involves cutting a muscle to relieve constriction, often performed in the gastrointestinal or urological systems. The procedure can alleviate symptoms caused by muscle-related functional obstructions, particularly in cases of achalasia, a disorder that affects the esophagus.
Heller myotomy – Muscles of the cardia (lower oesophageal sphincter or LOS) are cut, allowing food and liquids to pass to the stomach; Hymenotomy – Surgical removal or opening of the hymen; Hysterotomy – Incision in the uterus, and is performed during a Caesarean section; Laminotomy – The partial removal (or by making a larger opening ...

Pyloromyotomy is a surgical procedure in which a portion of the muscle fibers of the pyloric muscle are cut. This is typically done in cases where the contents from the stomach are inappropriately stopped by the pyloric muscle, causing the stomach contents to build up in the stomach and unable to be appropriately digested.
Diagram showing before and after an oesophago-gastrectomy. There are two main types of esophagectomy. A transhiatal esophagectomy (THE) is performed on the neck and abdomen simultaneously. [2] A transthoracic esophagectomy (TTE) involves opening the thorax (chest).
